feat: add pointer identification column to debug UI inspector

The raw fields grid now has a "Points to" column that uses
identify_pointer() to annotate each DWORD value:
- Static addresses: "→ CTASK_WORM_VTABLE"
- Heap objects with known vtable: "→ DSSound*"
- Fields inside tracked live objects: "→ DDGame.sound"

Pointer labels shown in light blue for visual distinction.
